My own experience: I have been using this eyeliner and some other eyeliners from this collection for about 3 months, and they never disappointed me. After having this liquid eyeliner, I never need to take out my mirror every few hours because my makeup always looked clean and perfect. I used to wear it for 12 hours and I didn"t even use any powder under my eyes. Key feature for this eyeliner: Great for Daily Use - highly resistant to tears, sweat & sebum, keeping your beauty more long lasting; Highly Black Finish - give you a pair of dramatic eyes & sexy look;Very Quick Drying Formula - Will be totally dry between 5-30 second; One of the BEST liquid eyeliner I ever used.Even this is not a name brand product, it will give you exactly what you need.(Smooth, Smudge proof, Without fading, Easy to use and etc.) You won"t be regret for your choice!---Contact us if you have any other questions.
